Once known as Lake of Carinola, it is a volcanic lake at the foot of mount Massico, in the municipality of Falciano del Massico.

The peak of Mount Miletto is reflecting in its placid waters where they come from.

It is an artificial lake, created in the 1960s to power the electricity station of Capriati al Volturno.

For the ancient Italic peoples it was a sacred river. On the shores, they erected sanctuaries such as the Demetra and Teano one.

Mount Massico with its 813 meters is the highest relief of the mountain range which starts from the slopes of the Roccamonfina volcano and reaches the Tyrrhenian Sea.

For the ancients, it was the river of the myth, which gave forgetfulness to whoever drunk its water.
